One of the Medieval siege weapons used during the Middle Ages was the Trebuchet. The Trebuchet was an invaluable Medieval siege attack weapon, similar to a catapult, which was used for hurling heavy stones to smash castle or city walls. Medieval engineers of the Middle Ages worked hard on the design of the Trebuchet to ensure that this siege weapon and the aim of this type of catapult, or sling, would have the greatest effect. The force of the Trebuchet was capable of reducing castles, fortresses and cities to rubble.
The word 'Trebuchet' is derived from the Old French word 'Trebucher' meaning to throw over. In England siege weapons, including the Trebuchet, was also known as the Ingenium from the Latin word ingenium meaning ingenious device! The Trebuchet is also referred to as the Trebucket.

This is superb. When do we storm the castle? After you've pounded it to gravel! I wonder if you made the weight wider (but shorter) if it would seem a bit more realistic? Or would it be mounted near a hole or on top of something so the weight could fall farther and really fling its payload with authority? At any rate, I love it1
